16. Applications and Implications

This week was to work and research more on our final project the documention for the final project can be found on the final project tap on the navigation bar.

Basically this week was to answer some of the important questions related to our final project.

Individual Assignment:

  • Propose a final project masterpiece that integrates the range of units covered, answering:
  • What will it do?
  • Who’s done what beforehand?
  • What will you design?
  • What materials and components will be used?
  • Where will come from?
  • How much will they cost?
  • What parts and systems will be made?
  • What processes will be used?
  • What questions need to be answered?
  • How will it be evaluated?
  • Your project should incorporate:
  • 2D and 3D design,additive and subtractive fabrication processes,
  • Electronics design and production,
  • Embedded microcontroller interfacing and programming,system integration and packaging
  • Where possible, you should make rather than buy the parts of your project
  • Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable.

Answers.

1. What will it do?

for my final project I will be building a crawler robot which can enable us to create a crawler drons, so that these bots help rescuers during disasters.

2. Who’s done what beforehand?

I would consider to look for project done on robots which has the machanism and design of such as crawler or six legs walking robots. So that it will help me work on my final project.

I went to browse on the google search engine of fabacademy website. The I got directed to the documentation of Yosuke Tsuchiya,2019 fabacademy student from Fablab Kamakura.

There under his application and implication assignment, he also explored on the machanism and design of six legs walking robots. Some of the projects are:

He has shared about four projects with a youtube video as shared below.

A very beautiful work of designing and creavity. But I was looking forward more towards six legs robots.

Dash Robotics has shared a very different machanism for a High speed crawwling bot and few glimps of other bots.

The video shown below is a six legs machinism and gave me certain ideas to work on.

This video was the best from all other. A small aestheically pleasing work of art. This one was the best.

3. What will you design?

  1. Design a PCB for the electronics on EAGLE or Kicad.
  2. Design a 3D printed Limbs of the robot on Fusion360.
  3. Design a laser cut Covering as the outside shell of the robot on Fusion360.
  4. Design a CNC cut body of the robot on fusion360.

4. What materials and components will be used?

  1. Plywood to make the body and the shell of the robot.
  2. 3D filiment for 3D printing.
  3. Copper plate for PCB
  4. ESP32 Wroom 32.
  5. 13 Servo Motor.
  6. One Ultrasonic Sensor.
  7. 3 Pin Audio Jack 2.5 mm.

5. Where will it come from?

Most of the parts are available in the fablab inventory and missing components will be ordered from digi key. Such as servos, Power modules and ultrasonic sensor.

6. How much will they cost?

The total cost would be around 80$ to 90$.

The servo motors cost around 5$ and one ultrasonic and power module will cover up other amount.

7. What parts and systems will be made?

For now my plan is to buy the servo motors, ultrasonic sensor and the power module from the market and other required parts will be made in the lab.

8. What processes will be used?

  1. 3D printing.
  2. PCB Production.
  3. Laser cutting.
  4. CNC cutting.

9. What questions need to be answered?

  1. Should use the MIT app to controll the robot or create a MPU6050 data transmitter.
  2. Power supply.
  3. How to minimize the size of the PCB.
  4. Programming Work.

10. How will it be evaluated?

My project should be successful if I am able to cover 3D printing to make the legs of the robot, PCB design and production while fabrication my controller board, Embrdded programming to interface with my robot. The making of shell will cover the process of laser cutting and CNC cutting if I decide to make the body of the bot. The input will be the ultrasonic to detect the nearest object on the front and the servos as the output for the motion of the robot. The robot should be controlled buy an app or by the gesture of our hand.
